Color paste, also known as pigment paste, is an important form of dye application, which is widely used in textile, ink, paint and other industries. In the classification of pastes, low-halogen pastes and ordinary pastes are two common types. They have certain differences in composition, performance and use, and the differences between the two types of pastes will be discussed in detail below. Fir...
The performance requirements of water-based varnish for printing paper glazing are as follows: 1.The film has good environmental resistance. Some of the printed matter after glazing is used to make all kinds of packaging cartons, in order to be able to play a good protective effect on the packaged products, the environmental resistance of the glazing film layer must be better. For example, the pac...
Ink scraping is not clean troubled many manufacturers, there are ten reasons for scraping is not clean, save it for use! 1.Ink viscosity is too high When the viscosity of the ink increases, the surface tension also increases correspondingly, and the force between them also increases, so that the scraper will increase the impact force of the ink on the scraper in the contact process with the ink, d...
First, material selection and preparation To make the resin crack effect, you first need to prepare the resin and pigment. Resin selection of high transparency, high hardness, wear resistance products, pigments can choose mineral pigments or metal pigments, you can also add a small amount of color pigments to prepare a rich color. Second, color mixing Mix the paint into the resin one by one and st...
Water-based ink is referred to as ink, and flexible water-based ink is also known as liquid ink, which is mainly made of water-soluble resins, organic pigments, solvents and related additives by composite grinding processing. Water-based ink is especially suitable for tobacco, wine, food, beverages, medicines, children's toys and other packaging and printing products with strict sanitary condition...

Paper ink absorption is not only related to the degree of porosity and capillary state of the paper, but also related to the surface properties of the paper fiber, the content of fillers, pigments, adhesives, ink composition and characteristics, printing methods, printing pressure and other factors. In actual printing, the absorption of ink by paper can be divided into two stages. The first stage ...
Rubber mold, silicone mold, shoe mold, latex pillow mattress mold, anti-stick easy mold Teflon spray, good model flon coating, non-stick mold surface treatment process The role of mold coating Molds are common tools in the manufacturing industry and are used to make a variety of products. In order to capture the service life and production efficiency of the mold, people often coat the surface of t...
The most important difference between non-stick cookware and ordinary cookware is that the surface is coated with a layer of non-stick paint, and the Teflon non-stick cookware commonly used on the market is to coat the main raw material of fluorinated resin such as polytetrafluoroethylene coating on the metal surface such as aluminum, copper or iron, and through sintering. Properties of NI-PTFE co...
In the face of different needs of different industries, rollers also need to do the corresponding coating treatment, so as to improve or compensate the relevant performance of the roller. So what are the surface coating technologies for rollers? 01 Coating treatment The coating treatment of the drum includes zinc plating, chromium plating, nickel plating, etc. The different coating treatment can i...
1.Ink The three primary color inks have different degrees of color bias, which will affect the color bias of the whole picture to different degrees. However, a small amount of color bias can be corrected from the ink preparation. When printing to grasp the gray balance of the ink used, the same amount of yellow, product, green do not produce neutral gray, they produce lighter, more turbidity with ...
Insufficient or uneven amount of glue due to insufficient amount of glue produced by the white spot can be observed in the composite machine. In the dry composite process, the coated adhesive must be able to fill the bumps and bumps on the surface of the ink and film to avoid appearance defects such as obvious white spots. When the water-based adhesive dry composite is used to produce lightweight ...
The hardness and softness of the water-based acrylic resin can be adjusted according to specific needs, but it is usually biased towards the harder side. First, the characteristics and application of water-based acrylic resin Water-based acrylic resin is an environmentally friendly water-based resin, with non-toxic, easy to clean, dry fast and other characteristics, widely used in furniture, packa...
The final state of waterborne polyurethane is a solid film. During the process from emulsion to solid film, accompanied by the evaporation of water and the concentration of water dispersion, the latex particles are close to each other. Before the solid content reaches 74%, the dispersion particles can move in the continuous phase of water. Under the influence of water/air interfacial tension, the ...
①The residual ink is converted into gray black ink According to the principle of color science, the complementary color of the ink mixed together, its hue will become gray black (red + green, yellow + blue-purple). Therefore, we can use this principle to deploy the complementary ink into gray-black ink by deploying the special color ink, and add it to the black ink in a certain proportion to use i...
